1.下载源码包：vsftpd-2.3.4.tar.gz
2.修改Makefile文件
CC     =    /usr/local/arm/arm-2009q1/bin/arm-none-linux-gnueabi-gcc
3.执行make，如果报错执行4
4.修改vsffindlibs.sh
屏蔽掉 50 51 54 行：# Look for libcap (capabilities)
if locate_library /lib/libcap.so.1; then
  echo "/lib/libcap.so.1";
#elif locate_library /lib/libcap.so.2; then
#  echo "/lib/libcap.so.2";
else
  locate_library /usr/lib/libcap.so && echo "-lcap";
#  locate_library /lib/libcap.so && echo "-lcap";
  locate_library /lib64/libcap.so && echo "-lcap";
fi
注：网上有文章说可以把库的路径设置到交叉编译器的库路径下，我没有试过，在此处采取屏蔽的方式。
5.make 成功
6.因为是动态编译，所以需要把动态链接库从编译器的lib下拷贝到跟文件系统的lib目录下


[root@uestc vsftpd-2.3.4]# file vsftpd

把所有的七个共享库拷贝过去

7.把生成的vsftpd 拷贝到跟文件系统的sbin目录下，把vsftpd.conf文件拷贝到 跟文件系统的etc目录下。
至此，arm-linux环境下的ftp服务器移植完成，下面开始对服务器进行配置。以下为一个简单的配置，不考虑安全性。

anonymous_enable=YES
local_enable=YES
write_enable=YES
anon_upload_enable=YES
anon_mkdir_write_enable=YES
dirmessage_enable=YES
xferlog_enable=YES
connect_from_port_20=YES
chown_uploads=YES
xferlog_file=/var/log/vsftpd.log
xferlog_std_format=YES
async_abor_enable=YES
nopriv_user=ftp
ascii_upload_enable=YES
ascii_download_enable=YES
ftpd_banner=Welcome to blah FTP service.
ls_recurse_enable=YES
listen_port=21
anon_other_write_enable=YES

8.在板子上创建必要的帐号，目录：
＃addusr nobody   //vsftpd 默认配置需要
＃mkdir /usr/share/empty//vsftpd 默认配置需要
#adduser -D /var/ftp ftp
#chown root:root/var/ftp
#chmod og-w /var/ftp
9.创建一个本地账户ming，创建好之后可以用ming登录
＃addusr ming
#passwd 123456
10.添加一个只能从ftp登录，而不能从本地的登录的用户mingming
＃addusr -G ftp -S /sbin/nologin mingming //-G -S 如果用-g -s 客户将不能登录：530 Login incorrect
#passwd 123456

11.服务器端执行 vsftpd /etc/vsftpd.conf ,客户端执行ftp YOUR_ADDR ,输入帐号名和密码即登入。
12.用cat /etc/passwd cat /etc/group 命令查看
